Thanks. I think I've figured out how to modify IDLE to do what I want.
Now, I'm having trouble figuring out how best to organize my changes so
they don't get clobbered by the next IDLE update. I'm trying to work
out how best to deal with packages and python namespaces. Here is a
sample of what I have worked out:
from Tkinter import *
EditorWindow = idlelib.EditorWindow.EditorWindow
format = '%d%b%Y.%H%M%S.log'
path = "E:/MyPythonProjects/"
filename = path + time.strftime(format)
log = open(filename,'w')
idlelib.PyShell.PyShell = MyPyShell
This seems to work. However, I don't really want the path to be
hard-coded into my program. I want to be able to select the directory,
and to control the logging behavior interactively. This means that I
will have to subclass ConfigDialog.ConfigDialog and perhaps other
classes as well. Am I likely to run into trouble with the approach
indicated above, and, in any case, is there a better way?
I realize that this question has little to do with IDLE development, but
I don't know where else to turn for help. I'd be grateful if some guru
will give of his wisdom to a beginner.
